ROLL POLISHED.

Application filed December 9, 1925. Serial No. 74,321.

This invention relates to certain new and useful improvements in roll polishers, and the primary object thereof is to provide continuously operated means true and even surfaces on the rolls of a rolling mill throughout the operation 'of the latter and without in any manner interferin with the rolling operations.

The invention further aims to provide equalizing means for the abrasive elements so as to maintain same under equal pressure in engagement with the rolls, thereby to eLfiect uniform polishing of the companion rol s.

The invention has still further and other objects which will hereinafter be set forth and manifested in the' course of the following descri tion. I

n the rawingsz- Figure 1 is a front elevation of the invention'applied to a rolling mill, parts being broken away and in section;

"Figure 2 is an enlarged 2-2, of Fig. 1;

- Figure 3 is an enlarged detail sectional view-on line 3--3, of Fig. 2, showing one of the abrasive carriers and its mounting means;

Figure -4 is a detail view ofone of. the bell crank levers;

Figure 5 is a section on line 5-5, of Fig. 4;

Figure 6 is a detail view showing the adjustment of the thrust means; and-- Figure 7 is a top plan view of the thrust means.

In proceeding in accordance with the resent invention, a pair of u per bell-cran lei lower bell-crank levers 2 are pivoted to the inner faces of the roll housings H' at points in substantial parallel aliuement with the upper and lower rolls R. Horizontal bars 3 have their ends secured to the vertical arms of the bell-crank levers so that the bars are supported in positions substantially parallel with the axes section on line of rotation of the'rolls R. The abrasive carriers or holders are composed'ofblocks 4; arranged in spaced order and provided with dove-tail mortises in their front faces in which are secured carborundum blocks 5.

' The blocks 4 have openings 6 through which slide or move the bars 3 extend so that the blocks may along the lengths of the bars.

for maintaining The blocks 4 have other openings through which rods .7 extend, the blocks being rigidly secured to the rodsby means of set screws 7'. The rods 7 are longitudinally movable in bushings 8 secured in transverse openings provided therefor and extending through one of the roll housings H.

The rods 7 are disposed in parallelism and are connected at their outer ends by means of a yoke 10 secured to the companion ends. of each of the rods, the yoke being centrally and pivotally connected by a pivot bolt 10' to one end of a pitman 11. The opposite end of the pitman is connected by means of a wrist pin 12 to a disk 13, the latter. being mounted on a shaft 14. A worm wheel 15 is mounted on the shaft 14 and is driven by a worm 16 on the shaft 17 of motor M; The disk 13 is provided with an elongated radial slot 18 whereby to enable the wrist pin 12 to be adjusted therealong so as to correspondingly adjust the'extent or degree of thrust of the pitman 11. The bars 3 are formed with journals 20 at their ends and which are secured in openings provided therefor in the vertical arms of the bell-cranks by means of set screws 21 whereby adjustment thereof for presenting the a rasive blocks to the rolls is provided for. A coil spring 22 is connected at its ends to the horizontal arms of the belLcranks and functions as an equalizer for the abrasive elements causing the latter to bear with uniform or equal pressure on the rolls.

In operation, the motor when in action, effects reciprocation of the pitman 11 and thereby yoke 10,'causing like reciprocation of the rods 7 and the abrasive elements. The rods and abrasive elements, as will be noted, are spaced away from the pass points of the rolls so that the roller can make passes without in' any way being hampered by" the presence of the invention. The abrasive carriers freely slide over the bars 3 and the latter are equalized in their relationto the rolls by means of the bell cranks and spring which act independently on the carriers.

Obviously, as many abrasive elements may be employed as is necessary to polish the entire lengths of the rolls, according to the distance of travel of their carrying rods 7.

What is claimed is- 1. In a roll polisher, upper and lower pairs of bell-cranks connected to the roll housings, a coil spring connecting the horizontal arms of the bell-cranks, horizontal bars secured at their ends to the vertical arms of the bell-cranks, longitudinally movable horizontal rods, abrasive holders secured to the rods and slidable upon said bars, a yoke connecting the rods, and means connected to the oke to reciprocate same.

2. In a roll polisher, upper and lower airs of bell-cranks connected to the roll ousing, a coil spring connecting the horizontal arms of the bell-cranks, horizontal guide has secured at their ends to the vertical arms of the bell cranks, a plurality of abrasive blocks slidable along said bars, said blocks being arranged in spaced relation, and longitudinally movable carriers for said blocks.

3. In a roll polisher, a pair of vertically alined bell crank levers mounted on the inner face of each roll housin guide bars carried in fixed relation to saidivers in parallelism to said rolls, a plurality of abrasive carrying blocks slidable on each of said bars, a longitudinally movable rod disposed parallel to each bar and having said blocks mounted thereon resilient means connecting the other arms of each pair of levers, and means for reciprocating said rods.

4. In a roll polisher, pivotally mounted levers, barsdisposed in parallelism to the rolls and'supported by said levers, holders slidable upon said bars, abrasive blocks carried by said holders, longitudinally reciprocable rods attached to said holders, means for reciprocating said rods, and tension means attached to said levers whereby the latter are caused yieldingly to hold said bars advanced to positions wherein said holders present said blocks in yielding contact with the rolls.

In testimony whereof, I afiix my signature,

HENRY D. WEISGERBER.
